  • Open a terminal window and type sudo poweroff, input your password when prompted, then press enter. (You will not get any feedback at all when entering the password.) Copy any messages printed in the terminal window and edit them into your question. Dec 20, 2016 at 0:44
  • Hello. @OrganicMarble It's works but I would like to do it from the button in the desk. How I could do this? I have Lubuntu 16.04.1 LTS Dec 20, 2016 at 1:06

  • Press CTRL + ALT + T
  • In terminal type sudo xedit /etc/modprobe.d/blacklist.conf
  • At the bottom of the file add:

    blacklist dw_dmac
    blacklist dw_dmac_core
  • Save and Quit

  • Type sudo xedit /etc/default/grub
  • In the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" erase quiet splash
  • Save and Quit
  • Run sudo update-grub
  • Reboot once

I did it and the PC now can PowerOff/Reboot/Suspend and everything.

Notes: This worked for ACER E-11 with previous Windows8.1 and now with Lubuntu 16.04.1 LTS.

Cons: During Start or ShutDown the computer will show only console, but it'll work.


You can use a Terminal and enter:

sudo reboot now

to force a direct reboot or

sudo shutdown -P

to shutdown and poweroff the maschine

  • Works, thanks @wooJoo I would like to solve the problem and do it from the button in pc. ¡could be there any solution? Dec 20, 2016 at 1:19

  • @LuigiLopez Please don't include the solution you found directly into your question, but write a separate answer to your own question yourself. That's the format of a Q&A site which we want to have here to keep the quality high and the structure clear. Thanks and welcome to Ask Ubuntu.
